It's looks like option 2 is more of a maybe than a definitive no, as in when we have concrete evidence then we'll really know whereas option 3 is saying that global warming is bollocks.

Is global warming happening? Yes and it is partly because of humans, we made the hole in the ozone worse BUT global warming does happen naturally anyway and has done so in the past. The problem isn't necessarily that global warming is occurring but that this time around it poses more of a danger to us than it would have before so the human race is a lot more vulnerable to problems such as crop shortages and changing weather patterns and here lies the issue, not that the Earth is warming but the impact it will have on us as a species and not to mention the impact it will have on the billions of other species we share the planet with.

I feel like the political rhetoric around invalidating this issue (Global Warming) is being attempted and is largely controlled by the corporate ultra-rich (i.e., Koch Brothers, etc). They have put billions into creating and funding think tank organizations that will discredit any and all science that does not support their use or abuse of the environment in order to increase their profits.

There is a disturbing trend to attempt to discredit ALL science, because it is based on theory. So, it then follows that any hard evidence (even if we are 99.9% sure) that can be produced is refutable because it is based on theory. It is this mindset that has been created by the corporate ultra rich and has been broadcast and fostered by the right media (Newscorp, Fox etc.) that even leads to the statement in your poll "NO. the science isn't settled".

For millennia, science has been the enemy of religion. Religion (in all it's forms and permutations) stands for one purpose: to exercise control over the masses and over you as an individual through fear and ignorance. All of the scientists and scientific discovery from the dark ages on had to conceal their studies that were not sanctioned by the Church. The Church did have clerics and vaults of libraries of all of the latest scientific discoveries and inventions, and often commissioned individuals to carry out their studies and research. The Church also held the results and repressed the dispersal of scientific knowledge in order to continue to control and manipulate the masses.

It should be no surprise that the conservative political dogmas are often supported and surrounded by religion. There is good reason that Evangelical Christianity has married the rhetoric of free market political conservatism/capitalism/corporatism. It conserves and controls a perception of a way of life that is unsustainable. The only way that you can maintain the status quo; vise-vi, unregulated development and unrestrained exploitation of the earth's resources, is by casting doubt upon the empirical method and sound scientific evidence.

In 2022, Earth is overpopulated and totally polluted; the natural resources have been exhausted and the nourishment of the population is provided by Soylent Industries, a food made by plankton from the oceans. In New York, when Soylent's member of the board William R. Simonson is murdered apparently by a burglar at the Chelsea Towers West where he lives, efficient Detective Thorn is assigned to investigate the case with his partner Solomon "Sol" Roth. Thorn comes to the fancy apartment and meets Simonson's bodyguard Tab Fielding and the "furniture" (woman that is rented together with the flat) Shirl and the detective concludes that the executive was not victim of burglary but executed. Further, he finds that the Governor Santini and other powerful men want to disrupt and end his investigation. But Thorn continues his work and discovers that the oceans have exhausted and the bizarre and disturbing secret of the ingredient used to manufacture Soylent Green. Written by Claudio Carvalho, Rio de Janeiro, Brazil A tale of Earth in despair in 2022. Natural food like fruits, vegetables, and meat among others are now extinct. Earth is overpopulated and New York City has 40 million starving, poverty stricken people. The only way they survive is with water rations and eating a mysterious food called Soylent. A detective investigates the murder of the president of the Soylent company. The truth he uncovers is more disturbing than the Earth in turmoil when he learns the secret ingredient of Soylent Green.

In the year 2022, earth's face has completely changed. New York's population, for example, has grown to 40 million mouths to feed. The greenhouse effect has risen the temperature into nearly unbearable regions, and the people are kept in the cities by law. The rich live in separated luxury apartments (with women as part of the rented furniture) but also experience the lack of natural food. Strawberries are at $150 for a glass of them. Police Detective Thorn investigates a strange murdering case of an official from the Soylent corporation, which feeds the masses with a palette of their creations: Soylent red, yellow, or, even more nutritious, green. Written by Julian Reischl <[email protected]>

The year is 2022. New York City has become overpopulated with 40 million people and pollution has caused the temperature to be risen and all natural resources have been destroyed, leaving 40 million people starving. The Soylent Company has create a new food product, Soylent Green. In the overpopulated and polluted New York City, police detective Thorn is assigned to investigate the brutal murder of an corporate official of the Soylent company, William R. Simonson. Thorn's investigation into Simonson's murder leads him to uncover a conspiracy in the Soylant company and the Soylent Green food product itself, where Thorn uncovers the horrible truth about Soylent Green. Written by Daniel Williamson

In the year 2022, overpopulation and the greenhouse effect have made life extremely difficult for the majority of people. The population of New York City is 40 million and the constant heat is unbearable. The city's infrastructure has broken down. Water is rationed and fresh food is virtually non-existent. Rather, most of the population live on soylent green, made from ocean vegetation and formed into tasteless green wafers. In this environment Detective Robert Thorn is assigned to investigate the death of William Simonson who was ultra-rich and didn't suffer any of life's hardships. He was killed with a blow to the head and it was all made to look like an interrupted break-in but Thorn is convinced early on that it was an assassination. Thorn learns that Simonson was a member of the Board of the Soylent Corporation but had recently become sad and morose. What, Thorn wonders would make such a rich man unhappy. Written by garykmcd

The most poignant scene was where Detective Thorn finds the Soylent Oceanographic Survey Report (that it is later discovered after being studied that the report explained that the earth's oceans were dying):

Returning to his apartment, Thorn gives Roth the Soylent Oceanographic Survey Report, 2015 to 2019, a two-volume work which he took from Simonson's apartment......Meanwhile, Roth examines Soylent's oceanographic reports at the "Supreme Exchange," a library and gathering place for fellow "books." The "books" and Roth finally realize that the reports indicate a "horrible" truth which, despite reading it for themselves, they find nearly impossible to believe; soylent green isn't made from plankton, it's made from human bodies.

Richard: ...is brought to you by Soylent red and Soylent yellow, high energy vegetable concentrates, and new, delicious, Soylent green. The miracle food of high-energy plankton gathered from the oceans of the world.

We can deny science or believe the propaganda of corporate greed until we are beyond all chance for the earth's recovery and restoration.

We aren't killing the Earth, we're killing ourselves. The Earth will survive and adapt regardless of what happened to us. Who knows, maybe the Earth is the one doing this as a way of "exterminating" it's pests.

Well, I'm not a scientist, but I am a Canadian, and I can tell you that "Global Warming" is a definite issue. Can we stop it? No! But we will need to learn to adapt or die.

The polar ice caps are melting. Need proof? The Polar bears are migrating further and further south (into areas inhabited by people) due to the lack of ice for them to hunt from. The Orca (Killer Whales) are migrating further and further north due to the melting ice fields, and are overtaking the polar bears as the main predator in the north.

Unfortunately, it's too late for us to do anything about it. Granted using non-fossil fuels may slow the problem, but at this point, we've basically screwed ourselves but good. The changing weather patterns, the melting glaciers, the migrating animals are all signs of the problem, to which there is no solution.

There is a theory that anthropogenic climate change is preventing an incipient minor Ice Age. Too, the real problem is that climate cycles tend to run on longer periods than most people are comfortable dealing with; the lag on ocean currents is between 500 and 1500 years. So, you want to know what causing current changes? Things that are contemporary with Martin Luther , Michelangelo, and Aztecs.
